Oxygen inhalation device clinical oxygen therapy

Abstract

The invention discloses an oxygen inhaling device for clinical oxygen transfer. The oxygen inhaling device is provided with a humidifying chamber shell the capacity of which is 150 to 300 milliliters and the periphery of which is a whole. The upper layer in the shell is an oxygen passage; the lower layer in the shell is a granular semi-fluid humidifying agent; an oxygen inlet hole and an oxygen outlet hole are arranged on the shell at two ends in the horizontal direction of the oxygen passage; the top of the humidifying chamber shell is provided with a feeding hole; and a sealed overpressure warning safety cover is arranged on the feeding hole. The humidifying agent is semi-fluid, and can fed directly through the feeding hole without needing to be heated, so that the shell keeps integral, has a firm structure, and is not broken by pressure when the pressure of oxygen is comparatively large; the oxygen inhaling device is not easy to be polluted by external bacteria; and the oxygen humidity can be over 50 percent RH at oxygen transfer, so that a patient has no risk of iatrogenic infection; no harmful volatile air is released; and no noise is generated.

Description

technical field [0001] The invention relates to an oxygen inhalation device for clinical oxygen transfusion. Background technique [0002] Oxygen infusion is a commonly used clinical nursing technique and rescue treatment. The relative humidity of the currently used medical oxygen is only about 3% when it is connected to the terminal. Direct inhalation will cause serious damage to the respiratory tract. Therefore, it must be humidified before entering the human body to avoid dry oxygen from irritating the respiratory mucosa. , improve oxygen therapy effect and patient comfort. The existing humidification treatment method is to pass oxygen through a humidification bottle filled with distilled water or saline, but there is no antibacterial and antiseptic system in the humidification bottle at present, and the cleaning cycle of the humidification bottle is as long as seven days. Therefore, the existing humidification bottle has actually become a bacterial culture medium. Alth...

The relative humidity of the currently used medical oxygen is only about 3% when it is connected to the terminal. Direct inhalation will cause serious damage to the respiratory tract. Therefore, it must be humidified before entering the human body to avoid dry oxygen from irritating the respiratory mucosa. , improve oxygen therapy effect and patient comfort

The existing humidification treatment method is to pass oxygen through a humidification bottle filled with distilled water or saline, but there is no antibacterial and antiseptic system in the humidification bottle at present, and the cleaning cycle of the humidification bottle is as long as seven days. Therefore, the existing humidification bottle has actually become a bacterial culture medium. Although the national health department has issued a microbial standard for humidification fluid, in clinical practice, even if the microbial index of humidification fluid meets the standard, it will still exist when the patient's resistance is low. High risk of iatrogenic infection. For example, Pseudomonas aeruginosa can multiply rapidly in a humid environment, and the biofilm formed adheres to the wall of the humidification bottle. Bacteria are stimulated to fall off, and mechanical friction is the main way to generate aerosols. Eventually, a large number of bacteria-carrying aerosols smaller than 5 μm will enter the alveoli and cause infection. A large number of literatures have reported that oxygen humidification fluids and oxygen therapy pipelines are contaminated by bacteria in clinical practice. It is more serious. In addition, when oxygen passes through liquid water, a large number of high-speed bubbles will form a large noise, which will also have adverse effects on patients.
